Title: Bally S5500 Error Code 84 Post by: TehPhreakshow on October 26, 2013, 10:03:30 PM Greetings community.
I have an older (1993 vintage) S5500 machine that has suddenly given me an error that no type of saferam clear will work on. It is error #84 (followed with 4 flashes of the button lights): RAM Error Volatile RAM failed to retain information during a self-test. Battery is checked an good. Thanks in advance!

Manual states the 4 "flash rate" is volatile RAM write/read failure (U67 & U68). I'm wondering if I can swap those same-numbered chips from my California Dreamin' machine to verify that the chips in the Black & White are bad without ruining my good chips.

Tried it again, per your suggestion. Still Get 84 code immediately on power up while holding pseudo coin & test buttons, jw10 in postion for safe ram clear. Also tried same procedure using clear chips, same result. |
